This (deprecated) routine is used to retrieve the transparency of widget backgrounds. It is recommended that the developer instead just retrieve the RGBA value for the background color and use the alpha value. (Note that alpha is the inverse of transparency).
int IWidget_GetTransparency(IWidget *pif, int *pnTrans)
AEE_SUCCESS - The background transparency was successfully retrieved AEE_EFAILED - The background transparency was not successfully retrieved
On successful termination, the value pointed to by the passed in pointer will be set to the background transparency value.
